Quadratic functionals of second order [PDF]

open access: yesTransactions of the American Mathematical Society, 1970
In this paper we study the minimizing of the general second-order quadratic functional (1.3) in a class of admissible functions y ( x ) y(x) with fixed endpoint conditions on y ( x ) y(x) and its derivative at x = a x = a

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

A General System of Functional Equations Deriving From Additive, Quadratic, Cubic, and Quartic Mappings

open access: yesJournal of Mathematics
In the current study, we introduce a system of functional equations (FEs) deriving from the mixed type additive–quadratic and the mixed-type cubic–quartic FEs which describes a multimixed additive–quadratic–cubic–quartic mapping.

On certain relations among the generating functions for certain quadratic forms [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The object of this article is to establish the relation between the generating function of the quadratic form 2m²+2mn+3n² and the generating functions for the quadratic forms m²+mn+n², m²+mn+2n², m²+mn+4n² and 2m²+mn+2n².

Symplectic Involutions, quadratic pairs and function fields of conics

open access: yes, 2016
In this paper we study symplectic involutions and quadratic pairs that become hyperbolic over the function field of a conic. In particular, we classify them in degree 4 and deduce results on 5 dimensional minimal quadratic forms, thus extending to ...

Breathable Graphene Oxide‐Polymer Composite Membranes With Two‐Step Barrier Mechanism Against Nerve Agents

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.

Lump Solutions and Resonance Stripe Solitons to the (2+1)-Dimensional Sawada-Kotera Equation

open access: yesAdvances in Mathematical Physics, 2017
Based on the symbolic computation, a class of lump solutions to the (2+1)-dimensional Sawada-Kotera (2DSK) equation is obtained through making use of its Hirota bilinear form and one positive quadratic function.

Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Response of pullets to digestible lysine intake

open access: yesCzech Journal of Animal Science, 2014
The objective was to determine the efficiency of utilization of lysine and to describe the responses of pullets to different digestible lysine intakes using three mathematical functions to estimate an optimal intake maximizing body weight gain and feed ...
